Application filed April 24, 1913. Serial No. 763,279. I

To all 'Lc/tom it may cono/.fm

.lle it known that l, (iiis'rav ll. 51mm., a subject ol the Emperor ot Germany, who l'iave declared my intention oi? becoming' a citizen ol the United States, and a resident.

oi. the city oit' Chicago, county of' Cook, and State of Illinois, have invented certain new and useful li'npi'oveinents in Balleai'ingir letainera, of which the following is a speci lication.

My invention relates to iinifiroven'ients .in hall bearingr retainers and hatI :For its object the production of a device oil this eliaractei.' which 'will be of extreniely Simple construe- `tion and etlicieiit in use.

Other objects Will appear hereinafter.

The invention consists in the eoinhinationy and arrangements of parte hereinafter de scribed and claimed.

.f e The invention will be best understood by reference to the accompanying drawing; 'forming a part of' this specification, and in Whieh- Figure Tl is a Side elevation ot' a ball bear- 525 ing' retainer embodying my invention, one

side thereof being brolien away in order to better illustrate the construction, Fig. Q ia a, section taken on substantially line :af-a; of Figi. l., Fig. 3 is an enlarged 'fragmentary J0 perepective View of one of the ineinbera coinprising the retainer, Fig'. 4 is a plan view of the blank 'from which each of the menihers comprising the retainer is formed, and Fig. 5 'is a view ot' one ot' the members of the retainer partly formed.

The preferred form of construction as illustrated in the drawing comprisesA two members which are eoi'interpai'ta ot each other. Said. :members are torined ot sheet 40 metal, each comprising an annular body por tion 1 and radially extending projections or ears 2 and i3 'provided at the outer and inner edges respectively ot the' portion Il as elcarl y Shown in Fig. 4.-. ln the formation of' the blank thus constituted into operative 'forni the portions 2 and 3 are bent to extend perpendiciilarly to the portion l or parallel with the axis thereof as clearly shown in Figs. and 5. llacl'i oi the portions and ,.5 bent, longitudinally upon itself ina 'forni fiibstai'itially wedge-shaped iu ei'( sS-Se :tioi'i.

The projections; Q and are alternately arranged aa Shown so that when the incinhers coi'nprising the retainer are arranged iit' together the 'projections 2 olf one will he ai'- i'aiiged iivl registration with the projections Cl ol the other so aa' to foi-ni spherical Socket` ioi' the reception of the hearing halls aa clearly shown in Fig. 1. ln order to hohl the ineinhei's conijiising the retainer againat relative movement bosses l are formed upon each of thev hotly portions l which are adapted to snugly engage or'intei'- loclt with the outer ends of the projections 2 and il ae will he readily understood. The projectione: are tornicd at theii` outer end` with ears 5 which are adapted to engage notches (i provided in the peripheries; ol the ineiiiberhl l in order to loch the parts together. the cara 5, a'l'ter engagement with the notches (i, heinff bent, over or clenched as clearly shown in Fig. l.

lt will he 'ohraci'i'ed that the two parte` of the retainer are exai'ftljY the saine in con. struction and ,ao that in the iiiiinufai'liire 75 thereof beth may be -l'orined from the saine die. 'lhe construction is extremely siniple and may he readily and easily arranged to accommodate a aci-ies of bearing halla in the inanuei' shown in Fig. l.

llf'hih l' the pi'el'ei'i'ed 'forni o't construction for carvying' iny invention into effect, this1 is capahle oi 'variation and inmlilication without dejiarting iiroin the spirit of the invention.4

llock with the outer ends olf the projet-,tions on the nher l'oi' holdingl said iuenihci's agaiuat i'elaiiie inovciniiil, aiihnlantially as described.

2.. hall hearing retainer comprising two annular inunda-r.: counterpartsy of: each substantially u'i-dne-nlmjled in crore; auction eoi'ipei'aliinf to loi'ni spherical Soi'ltcla for the recept ion ol' hearing; halls; and bosses on said annular ineinla-i'f. adapted to engage the free i-,nd ol' ,aaid projet-lione, suhfalanlially aa desci'ihed.

have ilhiati'ated and dezcribedy 3. A ball bearing retainer comprising tfwo annular nieinbers counterparts other; proections extending from one side of each of said members substantially Wedge-shaped in cross-section and-having recesses in their tree ends, said projections being adapted, when said members are arranged in operative relation With each other, to orin spherical sockets for tlie reception of bearing` balls; and bosses von said annular members, eacli boss engaging one of said recesses, substantially as described.

4f. [i ball bearing retainer comprising two annular inenibers counterparts of each other, eacli of said members being formed of a blank 'of sheet metal, said blank coinprising an annular body portion; and projections extending radially from the pe" ripliery or" said body portion, said projections being bentto extend perpendicular to said body portion and each being bent longtudinally upon itself into a form substantially Wedgesliaped in cross-section, the prog'eetions oit said members being adapted to` cooperate with each other to form spherical sockets Afor the reception of bearing balls; bosses on said annuler members adapted to of each' nosas?? body portion of each of said members, the

bosses of each of said members being adapt-- ed for engagement b the outer ends of the projections of the ot er, to bold said inem# bers against relative movement; and nie-ans for locking),` Said members together, substantially as described.

ln testimony whereof l have signed my name to this" specification in the presence oi two subscribing Witnesses.
